Goku, now back to his normal state, looks at Shazam in surprise. He had spent the entire fight reading Shazam's mind and analyzing his movements, something Shazam had been completely unaware of. In that brief moment of insight, Goku discovered Shazam's biggest weakness, and a plan began to form in his mind.
With a smirk, Goku steps forward, his voice calm. "You know what? I give up. You win," he says, surprising Shazam. "You're the better fighter." Shazam is flattered, his pride swelling at Goku's praise.
Goku drops to one knee in front of him. "Hey, can I get your autograph?" he asks innocently.
Shazam chuckles, "Of course, kid." He takes a pen and signs his name for Goku.
Goku takes the autograph, smiling. "Thanks... uh... Sha-bam."
Shazam corrects him with a laugh, "It’s Shazam."
Suddenly, Shazam instantly reverts back into his powerless child form of little Billy. Before he can react properly, Goku punches his arm clean through Billy’s torso, the force of the blow lifting him off the ground. He opens his hand, firing a ki blast that tears through Shazam’s body, obliterating him completely.
Within moments, all that remains is a pile of ashes.
Goku stands tall, brushing his hands off as he looks down at the remnants of Shazam. "You did just as good as Jiren in the Tournament of Power," Goku says, a touch of respect in his voice.
